<P>We ship frozen tissue all the time on dry ice Federal Express next day delivery. We usually have no problems with the tissue thawing. We prepare the package around 1/4 tissue and 3/4 dry ice. The more dry ice the better. We recieved a package of a brain hemisphere that was mostly tissue and very little dry ice. As a matter of fact it had all evaporated by the time we recieved the package and they shipped it next day delivery. The result was a partially thawed hemisphere that will probably not be much use to us. Just an example of bad frozen packaging and even less thinking. Some people do stupid things.</P>
